The TSA uses two types of imaging technology, millimeter wave and back-scatter. Currently, there are several hundred imaging technology units across 68 airports.
In March 2010, TSA began deploying 450 advanced imaging technology units, which were purchased with American Recovery and Reinvestment Act (ARRA) funds.
Advanced imaging technology screening is safe for all passengers, and the technology meets national health and safety standards. Learn more about the safety of AIT.
TSA has implemented strict measures to protect passenger privacy, which is ensured through the anonymity of the image. Additionally, advanced imaging technology screening is optional to all passengers.
